The twin propeller aircraft will fly at a slow speed of about 115 miles per hour over particular areas of the city in a straight line at an altitude between 500 and 2,800 feet to conduct chemical and radiological surveys in the area for about 30 minutes to an hour at an unspecified time, according to the EPA public advisory.

The flyover comes as a response to a request from the State of Texas to assist in environmental monitoring activities during events associated with the upcoming Super Bowl, the release stated.
